You all, that's how my mom use to play!!! It could be her at that piano, but three years ago (before her stroke). I'd swear on this. That was one of her signature pieces.

AND, OHHHHH, how I wish I could dance like that... at all, for that matter. The dancers' names are Maéva and William (Stuttgart), at least I think so... at the first of the video
Here they are on youtube: http://www.youtube.com/watch?v=CTJmm7OqU08

Is everyone up and dancing, yet?
